    Abstract: An encoder partitions into blocks using a set of block partition modes obtained by combining one or more block partition modes defining a partition type. The set of block partition modes includes a first partition mode defining the partition direction and number of partitions for partitioning a first block, and a second block partition mode defining the partition direction and number of partitions for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode includes only a block partition mode indicating that the number of partitions is three.

    Abstract: A coding device (100) is provided with a circuit (160) and a memory (162) connected to the circuit (160). The circuit (160): selects, from a plurality of tables which are used, during an operation, to correct a reference motion vector into a predetermined direction using a correction value designated by an index, and which have correction values with respectively different intervals between indexes, a first table used for a partition to be coded of an image in a moving image; writes a parameter indicating a first index to be selected from among indexes included in the first table; and codes the partition using the reference motion vector corrected by means of a correction value designated by the first index.

    Abstract: An encoder partitions into blocks using a set of block partition modes obtained by combining one or more block partition modes defining a partition type. The set of block partition modes includes a first partition mode defining the partition direction and number of partitions for partitioning a first block, and a second block partition mode defining the partition direction and number of partitions for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode includes only a block partition mode indicating that the number of partitions is three.
